tonight on "nightline" -- vanished. a mystery at 37,000 feet. a jet carrying hundreds of passengers simply drops out of the sky and disappears. tonight, an exclusive report. the secrets investigators found buried 2 1/2 miles under the sea. black box mystery. it's supposed to hold the clues to what went wrong. what was the captain doing out of the cockpit in the fury of the storm? and why couldn't he save this plane? dangerous skies. with investigators about to issue their final report, what will it tell families about what happened to their loved ones in those last terrifying minutes? and does it reveal a dangerous problem in the cockpits of our biggest jets?
11:36 pm
>> announcer: from the global resources of abc news, with cynthia mcfadden, bill weir and terry moran in new york city, this is a special edition of "nightline," vanished: the mystery of flight 447. >> good evening. i'm terry moran. it's one of the most astonishing aviation disasters in modern history. air france flight 447 from brazil to paris vanished three hours into the fight, 228 people were lost, flying aboard a state-of-the-art jet so foolproof it was called unstallable. so what went so catastrophically wrong? here's elizabeth vargas with a special "nightline" investigation. >> reporter: it is may 31, 2009. air france flight 447 prepares to depart rio de janeiro. 7:30 p.m., takeoff. it is it a routine 11-hour flight across the atlantic. the plane is filled with
11:37 pm
vacationers, businessmen, and families. destination? paris. 8:30 p.m., passengers settle in. there is no sign that one of the biggest mysteries in modern aif of yaigs aviation is about to unfold. among the passengers is ethna walls, an irish medical student and riverdance star on holiday in rio. ethna's sister is kathryn. >> her last text was saying she was getting on the flight. she'd had a brilliant holiday. >> reporter: ethna is on board with 215 other passengers, knowing their lives are in the hands of the men in the cockpit led by captain marc dubois. what they may not know is just how much the captain and his team depend, perhaps disastrously, on the sophisticated automated systems of the plane, the airbus a-330. it is considered to be among the
11:38 pm
safest airplanes in the sky. >> airbus is proud of the fact that they like to say their plane is pilot-proof. >> reporter: that's the good news. here is the bad news. is it true that, on any given flight, the pilots are at the controls only 3 minutes, 1:30 on takeoff and 1:30 on landing? >> that's about right. >> reporter: it is a cold fact of modern aviation -- planes pretty much fly themselves. the story of flight 447 has ignited a firestorm of controversy about pilot training in this new era of automated flight. >> we're moving towards automated operations where the pilot isn't even permitted to fly. >> reporter: 10:00 p.m., the flight is routine. the crew serves dinner, and some passengers settle in to watch an in-flight movie. but 30 minutes later, the plane, cruising at 37,000 feet, begins to enter a heavy storm system about 800 miles off the coast of brazil. instead of flying around the
11:39 pm
storm, it continues to fly toward it, keeping the automatic pilot system on. was that a bad decision? >> it was certainly a different decision than others took that night. >> reporter: other pilots on that same route choose to fly around the storm. more than 100 miles away from it. >> they were more cautious and did go a bit further away. >> reporter: at the same time, the location of the storm happens to coincide with a known dead zone of radio communication. out of reach of air traffic controllers on either side of the atlantic. 10:35 p.m., the last radio transmission from the air france flight, a routine call-out with flight coordinates. and then air france 447 vanishes. no one would ever hear from the crew again. it wasn't until 4:41 a.m., six hours later, that french air traffic controllers finally realized something is terribly wrong.
11:40 pm
by now, friends and family of the passengers are already waiting in the arrival terminal when word began to spread -- flight 447 has disappeared. >> this never happens. losing an aircraft on a cruise flight is just in itself extraordinary. >> reporter: for hours, french air traffic control tries in vain to locate the a-330. no other commercial jet in history has vanished so completely without a witness, without a distress call, without even a trace on the radar. as news of the missing airplane whipped around the globe, now it fell to the crash investigators to solve the mystery. they sent a dozen search and rescue ships to the crash zone. it would take them five days to find anything. by then, much of the wreckage had been dispersed by the ocean's current. only a fraction was recovered,
11:41 pm
and just 50 of the 228 people who were on board that night. many were believed to have sunk, still strapped in their seats, along with the plane and the black boxes to the ocean floor, what little rescue crews did find provided a few tantalizing crews. >> we know there was no because or bump because the aircraft was intact at the moment of the crash. >> and there are these clues. no oxygen masks were deployed. there was an empty jump seat with seat belts retracted and a life vest still sealed, floating in its packet. it seemed nobody had prepared for a crash. but, without the black boxes, the evidence posed many more questions than it answered. french investigators invested two years and about $50 million trying to find that airplane, all without luck. so finally they called in mike pursell and his team, the same organization that famously found the titanic. with this underground robot,
11:42 pm
purcell coaxed the atlantic to finally give up its secrets. >> we knew immediately that we had found the airplane. >> the robot returned with these photos, parts of the plane fuselage, other small aircraft parts, the galley. they also came back with something else. >> some human remains, definitely put the focus on that this was a real tragedy and a lot of people lost their lives. . >> reporter: not only did purcell's team find the black boxes in the wreckage, after two years in the water, they still worked. so when you heard what was on the black boxes, were you surprised? when we come back, you'll hear what was happening in the cockpit, the crew in chaos, and where was the pilot as flight 447 was going down? >> announcer: abc news "nightline" brought to you by geico. as a culinary manager i make sure our guests

two years after air france flight 447 suddenly disappeared, the plane's black boxes were recovered intact. they hold the clues to the series of unthinkable events that brought down the plane and, for the first time, shed disturbing light on what really happened in the cockpit in those final desperate moments. here again is abc's elizabeth vargas. >> reporter: it is 3 1/2 hours into the flight, almost 11:00 p.m., and the airplane is still cruising at 37,000 feet when captain marc dubois, a veteran air france pilot, makes a fateful decision. though his airbus a-330 is heading into a thunderstorm 800 miles off the coast of brazil, he gets up to take a scheduled
11:47 pm
rest break. he makes his first mistake of the evening when he failed to leave proper instructions to the two co-pilots who are now in charge of the flight. it is only a few minutes later that the plane's pitot tube, a piece of equipment that measures the air pressure, suddenly fails. this means the automatic pilot system shuts off. it's now 11:10 p.m. now control of the aircraft and the lives of the 228 people on board is in the hands of the least experienced of the three-man crew, cedric bonin. >> and the captain is sitting where i'm sitting now? >> yes. on the left side. >> reporter: bill vaz of the flight safety foundation and two test pilots joined us in an a-330 simulator to recreate what happened in the final crucial moments. >> the auto pilot disconnects? >> yes. let's see how that looks. there's a warning. the aircraft is now in my control. i have to fly it manually.
11:48 pm
>> reporter: all of a sudden, the computers are not in charge. cedric bonin, just 32 years old, is. at this point, captain bonin makes his first mistake. he should have just kept the plane flying. he shouldn't have changed anything. but instead he pulled the nose of the plane up? >> a dramatic pitch-up. >> reporter: raising the nose is the wrong thing to do and can cause the airplane to start falling out of the sky. it's the most baffling minute of the flight. the plane's stall warning goes off. >> stall, stall. >> reporter: but no one seems to pay any attention. >> stall, stall. >> it sounded for a total of 54 seconds, which is a long time. >> reporter: as the stall gets worse, the plane becomes harder to fall. on the black box recordings, bonin says, i don't have control of the airplane at all. by now, the other co-pilot is calling for the captain. where is he, he asks?
11:49 pm
then again, is he coming? they keep saying repeatedly, whoo's happening? what's happening? where's the captain? they call for the captain six times? >> yeah, yeah. >> where on an a-330 does the captain go? how far away from the cockpit? >> only a few feet away. you can get back in ten seconds. >> reporter: we don't know why, but it took the captain more than a minute, 60 crucial seconds, to return to the cockpit. two sources tell abc news that he was traveling socially with an off-duty flight attendant. were they together? >> when you are speaking of the private life of the pilot, we are not interested in that. >> reporter: but if the pilot is distracted because he's traveling with somebody, potentially, isn't that part of the investigation? >> i don't think it could be an explanation of accident. >> reporter: when captain dubois does finally enter the cockpit, he finds a scene of utter chaos. what's happening, the captain
11:50 pm
asks? i don't know what's happening, one of the co-pilots answers. what does that tell you about what's going on in that cockpit? >> it seems that the pilot did not understand the situation and they were not aware that they had stalled. >> reporter: within seconds, the plane has entered such a deep stall it is plummeting 120 miles an hour in the dark, belly first, with the nose slightly up. in the confusion, co-pilot bonin thinks his instruments are wrong. he asks, am i going down? by now the plane is pitching and shuttering as it falls. >> stall, stall. >> reporter: i got the chance to experience what that felt like in the airbus simulator. now we're going down, right? >> yes. >> stall, stall. >> reporter: in the cockpit, confusion has turned to chaos. both co-pilots are now trying to fly the plane in opposite directions. >> at a point of exasperation
11:51 pm
where you actually have a bit of discipline breaks down and you actually have both pilots trying to fly the aircraft. >> reporter: at what point, at what altitude, was this jumbo jet beyond saving? >> this aircraft got into a position where no one had ever designed it to be. realistically, somewhere in the area of 10,000 to 15,000 feet, they were really running out of options. >> reporter: it is too late, but it is not until the final seconds that the pilots realize the plane is doomed. and the very last words we hear on the voice recorder are from the pilot bonin who says, but what's happening? >> exactly. just complete confusion. >> reporter: those last words were not released by french investigators and only became public when they were leaked last year. why did you leave parts out? >> well, you know, you have some personal conversation that is
11:52 pm
not useful to the accident. >> but it's not personal. >> well, maybe i -- >> reporter: it is decisions like that which have led many people, including victims' families, to suspect that french authorities aren't telling the whole story about what happened to flight 447.

>> the airbus a330 is a plane so
11:57 pm
hi-tech and automated, human error is all but canceled out, but when computerized controls fail, some pilots lack the instincts or skills to stop the worst from happening. and for air france 447, the question still lingers, who is to blame for the 228 lives lost? once more, here's abc's elizabeth vargas. >> reporter: while there's no question that first officer bonin's decision to tilt the nose of the a330 up was a disastrous one, many experts believe there's more to the story than just incompetence in the cockpit. for example, those tubes that froze over in the storm, there have been 18 similar incidents since 2008. air france had already ordered the pitot tubes to be replaced over time with a better model, but the replacement for this airplane had not yet arrived before the fatal flight. >> why did the pilots refuse to
11:58 pm
fly those planes? >> we didn't know if it was just the pitot tube or it caused something else. there's been a big shift in the past few months. you don't hear that now. now -- >> what you hear now is a call for more pilot experience. >> yes. >> reporter: air france was so confident in the design of the airbus, it hadn't prepared its crews for the situation they found themselves in that night. >> no one was trained for high altitude stall recovery in the cockpit. >> reporter: nobody? >> no. >> reporter: why not? >> we've automated the environment and we really haven't revisited the old training. >> reporter: at the heart of this is a heated debate about so-called autimation addiction. pilots overly dependent on the computers flying their planes. >> because of this sophistication and the ability of airplanes to fly themselves, they don't have as much opportunity to actually fly the
11:59 pm
airplane. >> reporter: about 180 victims family members have sued air france and airbus, but airbus defends its claim and their design. what should every person worry about as we get on a jumbo jet today? >> you can't ignore the reality that the system got to be incredibly safe. >> reporter: and yet? >> it reminds us how human we are. the systems change. get over it. autimation is here. fine. how are we going to train people to intervene? >> reporter: the remains of more than 140 victims' bodies were recovered from the ocean. kathryn's sister was not among them. >> we didn't say goodbye. we would just love to see her one more time. >> reporter: what would you say? >> i probably would just give her a huge hug. >> her family settled its lawsuit. air france declined to comment
